  • Patent number: 11503819
    Abstract: Systems and methods for providing a combined mosquito staging and dissection system are disclosed. The system can include a mosquito staging subsystem; a robotic pick-and-place station; and a dissection, extrusion, collection, and disposal subsystem. The subsystems can include one or more stations to provide orientation, decapitation, extrusion of salivary glands, and disposal of carcasses of the mosquitoes. The resident live sporozoites from the salivary glands can be used to produce Plasmodium SPZ-based vaccines.

  • Patent number: 11443100
    Abstract: A method and apparatus for correcting character errors, an electronic device and a storage medium are disclosed, which relates to the natural language processing field and the deep learning field. The method may include: for a character to be processed, acquiring the score of each character in a pre-constructed vocabulary, the score being a score of the reasonability of the character in the vocabulary at the position of the character to be processed; selecting top K characters as candidates of the character to be processed, K being a positive integer greater than one; selecting an optimal candidate from the K candidates; and replacing the character to be processed with the optimal candidate if the optimal candidate is different from the character to be processed. With the solution of the present application, the accuracy of an error correction result, or the like, may be improved.

  • Publication number: 20220198137
    Abstract: The present disclosure provides a text error-correcting method, apparatus, electronic device and readable storage medium and relates to the field of natural language processing and deep learning. In the present disclosure, an implementation solution employed when performing text error correction is: obtaining a text to be processed, and an error-correcting type of the text to be processed; selecting a target error-correcting model corresponding to the error-correcting type; processing the text to be processed using the target error-correcting model, and regarding a processing result as an error-correcting result of the text to be processed. The present disclosure can enhance the flexibility and accuracy of text error correction.

  • Publication number: 20210402414
    Abstract: A wide-size-fraction flotation system and process includes feeding coal slime to be floated into a stirrer, adding water to the floating coal slime in the stirrer, stirring, then feeding same into a grading cyclone through a first feeding pump for pre-grading; after grading of the coal slime in the grading cyclone, feeding overflow in the grading cyclone into a flotation column through a second feeding pump for flotation, discharging flotation tailings through an underflow port of the flotation column, collecting flotation concentrates through an overflow port of the flotation column and feeding same into a bubble generator through a fourth feeding pump, and the flotation concentrates passing through the bubble generator and being fed from the bottom of a hydraulic flotation machine; and feeding underflow in the grading cyclone into the hydraulic flotation machine through a third feeding pump, for flotation and recovery.
